As DAMN and DARN are titles banks there is a temptation to load them using the TITLES command. Try to resist it! In the case of DAMN banks its a bad idea as DMM uses run number as validity rather than date and time. It minimises memory usage by loading and deleting banks as needed but it will not delete banks loaded via TITLES in case they are being used by other software.
Using TITLES is not forbidden but the titles cache take priority, so even for DARN banks it is recommended that all titles files are placed in the cache directly and the standard file naming convention is followed.
